A TTORNEY 1 FILTER ASSEMBLY FOR SWIMMING POOLS This invention relates toa filter assembly for a swimming pool and is particularly concerned withabove ground collapsable swimming pools made of a plurality of wallsegments joined together edge to edge to make ments and located on theoutside wall of the one segment, a filter chamber in the casing andcommunicating with the pool interior adjacent to the surface of thewater in the pool, a filter located in the filter chamber, and a pumplocated in the casing outside the filter chamber and communicating withthe filter and with the pool interior adjacent the bottom thereof forrecirculating the water in the pool from the top of the pool, throughthe filter and towards the bottom of the pool. A second chamber isprovided in the casing on top of the filter chamber and is connecteddirectly to the pool through an opening in the wall segment. Such secondchamber contains a basket filter for collecting the coarse materialinthe pool. I

- It is a second feature of the present inventionto prevent the filterpowder which is regularly fed into the filter chamber from depositingitself at the bottom of the filter chamber. r

In accordance with such second feature of the invention, theabove-mentioned second chamber is provided with a depression into whichthe basket filter is placed, and a conduit in communication with suchdepression is extended into the filter chamber for creating a turbulenceflow in the filter chamber to preventthe filter powder from depositingitself at the bottom of the filter casing. Such arrangement causes thefilter powder to be sucked in towards the filter discs of the filter.

a The second chamber is separated from the filter chamber by a removableplate permitting ac ress to the filter chamber.

The pump is located below the filter chamber in the casing and isprovided with a removable door giving access to the pump.

The invention will now be a preferred embodiment thereof and to theaccompanying drawings in which': 1

FIG. 1 illustrates a perspective view of a portion of a swimming poolwherein one of the wall segments comprises a pumpand filter casing FIG.2 illustrates a vertical section of the pump and filter casing; and

FIG. 3 illustrates a vertical cross-section of the pump and filtercasing. I 1

Referring to FIG. 1, there is shown va portion of a swimming pool madeof a number of wall segments 10 assembled together edge to edge. One ofthe wall segments comprisesa pump and filter casing 12 integraltherewith.

disclosed'with reference to As illustrated in FIGS. 2 and 3, the filtercasing 12 contains a recirculating pump 14 having an outlet 16 leadingto the pool interior through an opening 18 in the wall segment 10adjacent the bottom of the pool. Within the filter casing and above thepump 14 is positioned a filter chamber 20 having a concave bottom and inwhich are mounted hollow filter discs 22 opening at the center into amanifold 24 connected by a pipe 26 to the pump inlet 28.

Above the filter chamber in casing 12 is located a second chamber30'which is connected to the pool interior by an opening 32 through thewall segment 10. The opening 32 is closed by a bottom hinged float valve34 in a conventional manner. The bottom of the chamber 30 has adepression 36 therein in which is placed a basket filter 38 forfiltering coarse material. A conduit 40 is connected to the bottom ofdepression 36 and leads the water sucked in by the pump 14 along onewall of the filter chamber towards the concave bottom of the filterchamber so as to cause a turbulence flow preventing any accumulation offilter powder at the bottom of the filter casing, thereby causing thefilter powder to move towards the surface of discs 22.

Access to chamber 30 is through a removable top cover 42. Chamber 30 isseparated from filter chamber 32 by a plate 44 which is also removableto permit access to filter chamber 20. Filter chamber 20 is providedwith a drain tube 46 which maybe closed by folding the tube on itselfand locking it in position by a spring clip 48.

Access to the pump '14 and to the drain tube 46 at th bottom of casing12 is through a door 50.

Although the invention has been disclosed with reference to a particularembodiment thereof, it is to be understood that various modifications ofsuch embodi-. ment may be envisaged within the scope of the invention.
